Behavior of a hot-mix asphalt made with recycled concrete aggregate and crumb rubber
TL;DR: In this paper, an experimental program was devised to evaluate the effect on the resistance of a hot mix asphalt, due to the total replacement of a natural aggregate (limestone) by a recycled concrete aggregator.
Journal ArticleDOI
Mechanical Performance Characterization of Lignin-Modified Asphalt Mixture
TL;DR: In this paper, the authors investigated the effects of two lignin products (lignin powder and Lignin fiber) on the mechanical properties of asphalt mixtures, i.e., improved rutting resistance and thermal cracking resistance of asphalt mixture, degraded abrasion resistance, fatigue performance, and moisture stability.

Production of innovative, recycled and high-performance asphalt for road pavements
TL;DR: In this article, a specific laboratory study aiming at perfectioning recycled asphalt with high mechanical performance, for surface and structural layers of flexible pavements, was conducted, where the aim was to combine in the same material the maximum possible quantity of recycled asphalt (RA), coming from degraded asphalt layers, together with high structural performance of the recycled mixtures obtained (mainly stability, load spreading properties, rutting and fatigue resistance) that should not be lower, or possibly better than those offered by traditional asphalt mixture, made with virgin binder and aggregate.
Selection of laboratory aging procedures for asphalt-aggregate mixtures
TL;DR: In this article, the results of a preliminary investigation to evaluate aging methods for asphalt-aggregate mixtures were presented, and the effects of aging were determined using the diametral resilient modulus test.
